Nigerian oil workers have gone on strike at the Oleh crude oil flow station in the Niger Delta oil hub, saying they have not been paid, a labour union official said on Tuesday.

“The striking workers at Oleh flow station … besides the struggle for good pay and conditions of service are also asking for their rights to be unionised,” said Cogent Ojobo, Warri Zonal Chairman at oil labour union NUPENG. No more details were immediately available.
